WlRE-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 529,648, dated November 20, 1894,

Application filed March 23, 1894- Serial No. 504,837. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM E. GEEEN, a citizen of the UnitedStates, residing at Tiflin, in the county of Seneca and State of- Ohio, have invented certain new and useful Improvements in VVire-Stretchers, of which the following is a specification, reference being bad therein to the accompanying drawings, in which-- Figure 1 is a side elevation of my device applied to a fence wire; Fig. 2, a plan view thereof; Fig. 3, a detail side elevation of the hooked disk, and Fig. 4 a side view of the spindle.

This invention relates to that class of wirestretchers which-are adapted to be suspended on the fence wires and which consist essentially of a shaft or spindle, upon which the surplus wire is wound, and a hooked disk carried by said shaft and adapted to engage the fence wire at points diametrically opposite the shaft, as more fully hereinafter set forth.

Referring to the drawings, adesignates the shaft or spindle, which is squared at one end for the reception of a wrench and is headed, as at a, at its other end, said head being provided with a transverse slot a extending across the end of the shaft. Mounted upon the shaft loosely, so as to freely slide-thereon, is the disk b, the hub or eye of which is provided with a rib or lug b which fits in a longitudinal groove 1)" formed in the shaft, whereby the disk is free to slide endwise on the shaft but is compelled to rotate with it.

The disk is provided with a series of hooks b which project laterally from the edge of the disk and are all bent or turned circumferntially and in the same direction.

In applying the device to a wire, the wire is placed in the slot or groove a," and the shaft is then turned by means of a wrench or other tool. As the shaft is turned thesurplus .wire 'is wound upon the shaft and the wire on the opposite sides of the device drawn 5 taut. As the shaft and disk rotate the beveled or curved parts b of the hooks impinge successively against the wire and the disk is thereby slid along the shaft toward the squared end thereof. When the desired tension is obtained, the hooks engage the wires on opposite sides of the shaft and thereby prevent the tension from unwinding the sur-' plusage wound on the shaft. As will be seen the essential feature lies in mounting the hooked wheel slidably on the shaft, whereby said disk accommodates itself automatically to the amount of wire wound upon the shaft.

It will be observed that if the disk were mounted rigidly on the shaft, the wire would have to be bent or sprung in toward the hooks whenever the windings were not sufficient to extend in to the disk, and whenever the surplusage was more than sufficient to carry the windings to the disk, a second course of windings would be necessary and that would carry the disk away from the wires, as is obvious.

Having thus fully described my invention, what I claim is In a wire stretcher, the combination of a grooved shaft provided with means for engaging the wire at one end and at its other end with means for the reception of the wrench, and a disk slidably mounted on said shaft carrying a lug, working in the grooves therein, and a series of lateral books 12 said hooks being turned or bent in the same direction and beveled on their outer sides, as at 19 substantially as herein shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

WVILLIAM E. GREEN.
